Vimokṣa-niścaya: Pañcaśikha’s Analysis of Aggregates, Guṇas, and Tyāga (मोक्षनिर्णयः)
तद्धत् संसारकान्तारमातिष्ठ न् श्रमतत्पर: । यात्रार्थमद्यादाहारं व्याधितो भेषजं यथा
tadvat saṃsārakāntāram ātiṣṭhan śramatatparaḥ | yātrārtham adyād āhāraṃ vyādhito bheṣajaṃ yathā ||
同样,安住于世间生涯之林而勤于正业者,当以食为资粮,仅为支撑生命之旅;如病者服药,非为享乐,唯为保全。
भीष्म उवाच
Food should be taken with restraint and purity, primarily to sustain life and support one’s duties, not to indulge the palate—like medicine taken by a patient for survival rather than enjoyment.
Bhīṣma continues his instruction in the Śānti Parva, using the metaphor of saṃsāra as a dangerous forest to advise disciplined living: the householder should work diligently and eat only what is necessary for maintaining life.
